Test Method 112-2008
Determination of: Sealed Jar Method
Developed in 1965 by AATCC Committee RR68
1. Purpose and Scope
1.1 This test method is applicable to textile fabrics that evolve formaldehyde, particularly fabrics finished with chemicals containing formaldehyde. It provides accelerated storage conditions and an analytical means for determining the amount of formaldehyde released under the conditions of accelerated storage.
2.1 A weighed fabric specimen is suspended over water in sealed jar. The jar is placed in an oven at a controlled temperature for a specified length of time. The amount of formaldehyde absorbed by the water is then determined colorimetrically.
